get_Yit: get_Yit

In BMisc: Miscellaneous Functions for Panel Data, Quantiles, and Printing Results

get_Yit

Description

A function to calculate outcomes for units in a particular time period 'tp' in a panel data setting (this function can also be used to recover covariates, etc. in the first period).

Usage

get_Yit(df, tp, idname, yname, tname)

Arguments

df	the data.frame used in the function
tp	The time period for which to get the outcome
idname	name of column that holds the unit id
yname	name of column containing the outcome (or other variable) for which to calculate its outcome in the immediate pre-treatment period
tname	name of column that holds the time period

Value

a vector of outcomes in period t, the vector will have the length nT (i.e., this is returned for each element in the panel, not for a particular period); 'NA' for units not observed in period 'tp'

Examples

n <- 50
id <- rep(seq_len(n), each = 4)
t <- rep(1:4, n)
y <- rnorm(n * 4)
dta <- data.frame(id = id, t = t, y = y)
Yit2 <- get_Yit(dta, tp = 2, idname = "id", yname = "y", tname = "t")
length(Yit2) ## n * 4
